Dear All, I am trying to integrate Openstack + vCenter + Neutron + VMware dvSwitch ML2 Mechanism driver.
I deployed a two node openstack environment (controller + compute with KVM) with Neutron VLAN + KVM using fuel 5.1. Again I installed nova-compute using yum in controller node and configured nova-compute in controller to point vCenter. I am also using Neutron VLAN with VMware dvSwitch ML2 Mechanism driver. My vCenter is properly configured as suggested by the doc: https://www.mirantis.com/blog/managing-vmware-vcenter-resources-mirantis-openstack-5-0-part-1-create-vsphere-cluster/ I am able to create network from Horizon and I can see the same network created in vCenter. When I try to create a VM I am getting the below error in Horizon. Error: Failed to launch instance "test-01": Please try again later [Error: No valid host was found. ]. Here is the error message from Instance Overview tab: Instance Overview Info Name test-01 ID 309a1f47-83b6-4ab4-9d71-642a2000c8a1 Status Error Availability Zone nova Created Jan. 9, 2015, 8:16 p.m. Uptime 0 minutes Fault Message No valid host was found.

It looks like my issue is similar to this : https://ask.openstack.org/en/question/43594/vmware-neutron-bridging-problem/ I have configured br100 with VLAN ID 103 in vCenter. But I don't have br100 in my controller node. Not sure how to create it in my controller. *NOTE :* I have another openstack environment which I deployed as vCenter Environment using Fuel 5.1 and manually installed/configured Neutron + VMware dvSwitch ML2 Mechanism driver. It works fine with same vCenter. Any help? I happy to provide more info if required. -- Thanks & Regards E-Mail: thefossg...@gmail.com IRC: neophy Blog : http://lmohanphy.livejournal.com/
